Another quick post on the topic of designing product packaging with the entire life-cycle in mind, from acquisition to disposal or secondary use. These are Heineken bottles from the 1960s designed to double as bricks once the beer is consumed. Inhabitat: "The final WOBO [world bottle] design came in two sizes - 350 and 500 mm versions that were meant to lay horizontally, interlock and layout in the same manner as ‘brick and mortar’ construction. One production run in 1963 yielded 100,000 bottles some of which were used to build a small shed on Mr. Heineken’s estate in Noordwijk, Netherlands."
